Photosynthesis & cellular respiration

Respiration is a process in which energy is released due to the breakdown of glucose molecules with the addition of oxygen forming carbondioxode, water and energy in the form of Adenine tri phosphate (ATP).

Photosynthesis is a process in which energy is produced in the presence of sunlight. In photosynthesis reaction, plant take water from the soil and carbondioxide from the surrounding air through stomata produces oxygen and glucose.
